Shell has warned investors that it will take an impairment charge of up to $2bn (£1.6bn) in its next set of results after it was forced to halt work on Europe’s largest biofuel project and sell off a Singapore refinery.
The oil company told investors to expect a non-cash writedown of between $600m and $1bn when it publishes its second-quarter results next month because of trouble at a major biofuel project in Rotterdam in the Netherlands.
